Almost everyone on this thread is referring to removing the check-in functionality as the death of Foursquare as a consumer product. Y'all - Foursquare did that because it was not just dying but basically dead. The change allowed them to be more flexible in the new phase of the company. It might not have worked the way they dreamed (I don't know) but Foursquare was crashing fast at the time of the split.
